SPECIFICATION forming part of Letters Patent No. 734,486, dated July 21, 1903.

' Application filed May 1, 1903. Serial No. 155,095 (No modeli) T at whom it may c0ncerm- Be it known that I, THATCHER P. WILSON, of Easthaven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Water-Stills; and I do hereby declare the following, when taken in connection with the accompanying drawings and the figures of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a view invertical section of one form which my improved portable water-still may assume,the float being shown in its lowest position and the valve open; Fig. 2, a correspending view with the float inits highest position and the valve closed, Fig. 3, a view in horizontal section on the line a b of Fig. 1; Fig. 4, a broken view, in side elevation, showingthe upper end of the float, the tubular valve, and the lower end of the tubular valveseat; Fig. 5, a broken view of the same parts in vertical section; Fig. 6, a broken view, in

side elevation, of the upper ends of the feed-' tube and the cut-ofi tubeand showing the coupling-rod by broken lines; Fig. 7, a detached broken view, in side elevation, of the upper end of the feed-tube; Fig. 8, a corresponding view of the coupling-rod.

My invention relates to an improvement in portable water-stills, the object being to produce a simple, compact, effective, and convenient automatic apparatus constructed with particular reference to being easily cleaned and to being'us'ed on the top of an ordinary kitchen stove or range.

With these ends in view my invention consists in a portable water-still having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In' carrying out my invention as herein shown I employ an upright cylindrical tank 2, having a fiat bottom and open at the top. Into theopen upper end of this tank- I set a tapering independently-formed cold-water reservoir 3, having a concaved bottom 4: and

formed near its upper end with a circumferential outwardly projecting bead 5, by which it is supported in the upper end of the'tank, above which its upper end projects. The

main portion of the reservoir 3 is made enough tom portion of the tank. A cock 10 is set into the tank'just above the bottomof the distilled-water chamber 8 for drawing ed the distilled water.- In the centerof the bottom 1 of the reservoir 3 I mount a long vertically-arranged feed-tube 11, rising at. its upper endto the top of the reservoir and projecting at its lower end through the bottom thereof. A bridge 12, secured to the bottom of the reservoir 3, reinforces the said tube.v A tubularvalve-seat 13, larger in diameter than the feed-tube 11 and arranged concentric therewith, is secured at its upper end to the lower face of the said bridge 12 and extends downwardly to thelowerendof the feed-tube, there being an annular valve-space 14 between them. A tubularvalve 15, centrally mounted upon the upper end of a float 16, isadapted in diameter and thickness to enter the said space,

in which it fits so closely as to form a water-t tight joint. It is formed at its upper end at opposite points-with two vertically-arranged slot-like discharge-openings 15, which, according to the position of the float, are exposed below the lower end of the tubular valve-seat 13 or located entirely Within the same. The

upper edge of the said valve 15 is formed with 1, it will register with a corresponding feedport 20, formed in the feed-tube 11 near the bottom of the reservoir 3.

holder that the cut-off tube 18 may rise and fall with the float, I provide the same with a long coupling-rod 21, rising from the center of the tubular valve 15 and extending upward through and nearly to the upper end of the feed-tube 11 and there flattened and formed with a transverse hole 22, receiving a coupling-screw 23,passing through transverse holes formed in the upper end of the cutoff tube and also passing through two oppositely-arranged long vertical slots 25, formed in the upper end of the feed-tube. Under this construction the cut-off tube rises and falls with the float 16, which is thus permanently connected with the reservoir 3, so that the same and the float may be removed and inserted into the tank 2 virtually as one piece.

To provide for the aeration of the distilled water, I locate within the tank 2 a vertical air-supply pipe 26, to which air is admitted through a cook 27 and which at its lower end opens into a segmental air-chamber 28,form ed by locating a segmental plate 29 within the shell 7, to which its lower end and its sides are secured, the said chamber being open at the top. Under this construct-ion air entering through the pipe 26 is discharged, so to speak, in a broad flat current or sheet into that portion of the condensing-chamber 6 located directly below the bottom of the'reservoir 3. The upward draft of the steam rising from the retort into the condensing-chamber creates a suction which operates to draw in sufficient outside air to thoroughly aerate the distilled water. \Vhen in the operation of my improved portable water-still the float'16 descends sufficiently in the retort 9 to expose the lower ends of the discharge-openings 15 of the tubular valve 15 below the lower end of a-tubular valve-seat 13, water will be fed from the reservoir 3 into the retort, for at this time the feed-ports 19 and 20 are in partial or full registration, owing to the corresponding downward movement of the cut-off tube with the float. As the water rises in the retort the float will be lifted and the flow of water gradually out off. Then when the lower ends of the openings 15 are lifted entirely above the lower edge of the valve-seat 13 the water will be entirely out oif, not only at the valve, but also at the feed-ports 19 and 20, which will by this time be entirely out of registration, for the reason that the cut-off tube 18 moves .up and down simultaneously with and to the same extent as the float with which it is coupled, as described. The action of the apparatus so far as the feeding of water into the retort is concerned is thus made automatic.

I would have it understood that I do not limit myself to the exact construction shown and described, but hold myself atliberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a portable water-still, the combination with a tank containing a retort and a distilledwater chamber, of an independently-formed water-reservoir adapted to be set into the upper end of the said tank, a vertically-arranged feed-tube mounted in the bottom of the reservoir and projecting downwardly therefrom, a float, a valve located at the lower end of the said tube and controlled for feeding and cutting off the water by the action of the said float, a cut-off located within the reservoir and coacting with the upper portion of the feed-tube for admitting water thereto and excluding it therefrom, and means connecting the said cut-0E with the float whereby the valve and cut-off act together.

2. In a portable water-still, the combination with a tank containing a retort and a distilledwater chamber, of an independently-formed water-reservoir adapted to be set into the up per end of the said tank, a vertically-arranged feed-tube mounted in the bottom of the reservoir and projecting downwardly therefrom, a tubular valve-seat inclosing the projecting lower end of the feed-tube and larger in diameter than the same so as to form a valvespace between them, a float, a tubular valve carried thereby and adapted to enter the said valve-space and formed with discharge-openings, a cut-off tube inclosing the upper portion of the feed-tube and formed with a feedport registering with a feedport formed therein, and a coupling-rod secured to the float and extending upwardly into the feedtube and connected with the cut-off tube, whereby the same is caused to rise and fall with the float.

3. In a portable water-still, the combination with a tank containing a retort and a distilledwater chamber, of an independently-formed water-reservoir adapted to be set into the upper end of the said tank, a float,a verticallyarranged feed-tube mounted in the bottom of the reservoir, a valve automatically operated by the float and located at the lower end of the said tube, and a cut-off located within the reservoir and connected with the float so as to operate simultaneously therewith.

4c. In a portable water-still, the combination with a tank, of a shell located in the lower end thereof and having the form of a truncated cone and producing a distilled-water chamber and a retort, an independently-formed water-reservoir adapted to be set into the upper end of the said tank, a float located in the retort, an automatic valve operated by the said float for feeding water automatically from the reservoir into the retort, a segmental plate located on the insideof the said.
